This invention relates to frames for window screens and particularly to frames adapted tofit the entire window opening and provided with a shade roll type of screen.

In addition to being constructed in many different sizes, window frames vary materially in size even where intended to be uniform. Hence, the usual practice was to construct a screen frame to fit the measurements of a particular window frame. The impracticability of such practice is quite apparent. Also, a frame so constructed was fitted with a screen which was fixed and, of necessity, had to be applied outside the window sashes where it was exposed to the deleterious action of the weather. The provision of this type of screen for casement windows has not successfully been accomplished heretofore.

The present invention, therefore, seeks to provide a screen frame, adjustable for size within certain limits, and adapted to support and clamp a shade roll type of screen in any adjusted position of said screen.

The invention further seeks to provide a screen frame which may be universally applied to either sliding sash windows or casement windows, by applying said frame on the room side of the window frame, access to the windows being had through the frame opening.

The invention also contemplates the provision of improved means for varying the size of a screen frame as contemplated in this invention.

Another contemplated feature resides in the provision of simple means for effectively clamping said screen in any adjusted position in said frame.

The foregoing features which are broadly stated and many others, more specific, will be more clearly apparent from the following detailed specification based on the accompanying drawings which illustrate a preferred embodiment of the invention.

, In the drawings:

Fig. 1 is a front view of a screen frame constructed in accordance with this invention.

Fig. 2 is an enlarged vertical sectional View as taken along the line 22 of Figure 1.

Fig. 9 is a sectional detail view as taken along 5 the line 99 of Figure '7.

Fig. 10 is a cross-sectional view to an enlarged scale, of the screen edge clamping means as taken along the line ii!l0 of Figure 3.

Fig. 11 is a similar View showing the screen edge clamping position of said clamping means.

Fig. 12 is a View similar to Figure 11 of an alternate form of screen edge clamping means.

Fig. 13 is a front view of a non-adjustable frame constructed in accordance with this invention.

Referring to the drawings in greater detail, the frame is preferably formed of four L-shaped members i5, l6, l7 and E8, the horizontal leg IQ of the member l5 being telescoped within the leg 29 of the member I6, the horizontal leg 2! of the member 18 being telescoped within the leg 22 of the member !1, and the vertical legs or stiles 23 and 24 of the members I? and 58 respectively, being telescoped within the stiles 25 and 26 of the respective members 16 and I5.

As can be noted from this structure, the frame may be varied in the size of both the length and width dimension to a degree commensurate with O the amount of telescopic engagement of the various leg portions of the members comprising the frame.

The elements or members of the frame are each preferably formed with a U-shaped section having the ends of the U turned inwardly as shown in Figures 7 and 10. In this manner there is provided guideways 27 for the side edges of a screen 28 on a spring roll 29 mounted in a casing 36 carried by the element I! of the frame. The bottom edge of the screen is preferably provided with a stiffening member 3| provided with a lip or flange 32.

At each point of telescopic engagement between cooperating portions of the frame elements there is preferably provided means for locking said portions in adjusted relation. Since all of these means are substantially alike, only one, will be described, the one shown at the lower left hand corner of the frame being chosen.

The outer leg 2!! is preferably provided with pairs of opposed guides 33 in which a casing 34 is arranged to slide. The top and bottom walls of this casing are each provided with a slot 3G in which is guided a cross pin 35 secured to a dog 36 guided in a slot 31 in the casing 34. The dog 36 is formed with a lug 38 normally projecting through an opening 39 in the leg 29 and engageable against one of the edges 45 of a plurality of slots M in the telescoping leg E9. The dog 36 is, also, preferably formed with a projection 42 for the purpose of releasing said lug 38 from engagement with an edge 513.

Between the edge 53 of the dog 36 and the end wall id of the casing there is preferably arranged a coil spring 45 and, if desired, said spring may be provided wth a tubular cap @6 as shown.

At the open end of the casing E i and pivoted at 47 thereon, there is provided link means d8 connected to an intermediate portion at 49 to a toggle lever 56 mounted on the pivot pin M on a fixed lug 52 on the leg 20.

In association with the end wall M of the casing 3 there may be provided a lug 53 on the portion 28.

When a screen frame is to be applied to a window frame, the toggle lever 59 is lifted as shown in Figure 6 permitting the housing to abut the lug 53 and thereby raising the dog 38 so its lug 3% assumes a position upon the outer surface of the member Zil. The screen frame elements are then adjusted in proper relation, i. e. against the jambs, sill, and top rail of the window frame.

The toggle lever 56 is then rocked down to the position shown in Figure 5, exerting a pull on the casing 3 and, through the medium of the spring 25, forcing the dog 36 so the lug 38 thereon engages that edge d of the slots M which isin its path. Since the pivot is out of line with the pivots 41 and 49 the toggle lever 50 will retain its position until released. Also, since the slot 39 is long enough to include one of the slots 4! and a bridge portion therebetween, quite fine adjustment of the screen frame can be obtained.

The spring 4.5 forces the dog 36 and; therefore, the frame element I5 in one direction, and the casing 35 and, therefore, the frame element iii in the opposite direction. This insures positive positioning of the screen frame within the window frame.

The screen 28 may be pulled down to any selected intermediate position in the frame or completely down and clamped in that position. A preferred means for accomplishing this, here disclosed, comprises a handle 54 pivoted at 55 to the element 20 of the frame, and through links 56 and 5'? and slide rods 58 and 59, is adapted to rock the shafts 60 and ti through the medium of the lever 62 and 63.

The shafts 6E and 5| are mounted in bearings 65 and extend upwardly to a point beyond the middle of the frame. Upon these shafts are fixed a plurality of clamps 65 which through openings 66 in the frame are adapted to impinge on the edges of the screen as shown in Figure ll. In order not to mutilate the screen the clamping portions of the said clamps may be lined with a material such as leather or feltas shown at 61.

If desired, as shown in Figure 12, the clamps 65 may be engaged-against one of the inwardly bent portions 68 of the elements of the screen frame which in turn is urged to impinge the the slide bars 58 and 59 are provided with offset portions H which force the portion 2|] of the leg 26 into engagement with said stiffening member through the medium of the loops 12 as best seen in Figure 9. The released and gripped conditions of said stiffening member are clearly shown in Figures 7 and 8 respectively.

It is, of course, understood that the screen clamping means may be employed on a nonadjustable frame, as shown in Figure 13 and, similarly, the adjusting means here disclosed may be used on screens having other screen clamping means.

As can be understood from the foregoing, a screen frame has been provided which may be expeditiously applied to either at sliding sash or casement window and is adapted, by the mere. manipulation of a single handle, to clamp a screen therein in any required position. It is also ap-. parent that immaterial changes in construction and in the arrangement and sizes of the parts may well be made without departing from the true spirit and scope of the invention as hereinafter claimed.
